Moving parts, sand, unseen wear, maintenance, heavier, way more expensive RRP, filding around on one side of the bar in gusty situations - one steering side, harder to release under load, the dodgy china stainless trust equation "we promise its 316", potential shear forces too - unlikely but possible - any thing is possible.
Such an necessary risk adding more complex mechanical components than a traditional cleat for no benefit at all really
Well enjoy your click bars and similar if that is the kind of thing you like.They are the work of a very recently graduated engineer in my eyes, if graduated at all, and more importantly with no extensive experience in kiting.
There are moving parts in front line trim systems. Which have to hold a lot more force for extended periods of time.
I have had zero maintenance on the adjustment mechanism over two years. I do open the ends up twice a year to inspect.
Sand is not an issue.
The bar is heavy but it is not because of the winding mechanism.
It is roughly the same cost as other top of the line bars.
Whether you adjust the front lines or the rear lines, you have to remove one hand from the bar. The push button depower and rotate to power, is much less fiddly than using a cleat. It is quite easy to do when riding one handed.
I don’t think it is much harder to release under load.
Dodgy Chinese stainless is a universal problem. There are plenty of stainless pieces in bars that you are trusting.
There is no potential shear forces, there are shear forces. Including the shear on the pins used in front line adjustment systems. Those are the components that bother me.
However, stainless steel is pretty strong stuff Those little 6mm pins will hold over 10000 lbs in shear.
There are cleats and pulleys and pins, and ropes, and webbing in front line adjustment systems which are under a higher peak and continuous load.
There are performance advantages to having a repeatable power adjustment system. Also since it quick and repeatable it opens up possibilities to adjust on the fly, even on a wave face. You can increase power with no line tension. You can have a long throw and still adjust the power, important for smaller people.
Simple and clean visually.
You do not have to have a bungee in the depower line or have it loose.
Frankly, it is hard to go back to a cleat adjustment after using a click bar.
They are not the work of a single recently graduated engineer. But rather a team and it is obvious a lot of time was spent on development and making it manufacturable and fool proof.
